if Appli cation August 11, 1941s; malar a-6 9 1 present inventionrelates generally to snow removal apparatus, and more particularly to anovel device which maybe employed effectively to clear snow, sleet,-andice from the lower section .of roofs and, from. guttersby an" individualstanding within a building.

In all climates where snowfal lls' anag ious' condition I now ariseswhenever' large amounts of snow accumulate upon the'roofs'and in thegutters, of buildings, particularly dwelling houses having slopingroofs. As a result of alternate thawing and freezing weather aided bythe warmth of the roof itself, the snow gradually changes to water whichtrickles down toward the colder snow on the eaves or gutters which tendsto soak it up and freeze into a solid dam of ice. This causes such waterthereafter to back .up under the slates or shingles and 'to leak downinto the building, thus damaging walls and ceilings.

This is most annoying and often a very costly condition, and as far as Iam aware there have never been any mechanical means devised which willovercome this diificulty other than the tedious and dangerousundertaking of climbing up a ladder and removing the snow from theoutside.

By my novel construction, a person can readily free his roofs from snowafter each storm without any appreciable effort and without going out inthe cold to effect the same. By standing on the floor below the roof,opening the window, and adjusting my apparatus into operative position,he may scrape off the snow by merely manipulating a convenient handlever.

A main object of my invention, therefore, is to provide a foldable unitwhich may be projected thru an open window, manipulated intoroof-engaging position and operated by a person standing inside abuilding, and which includes provision for removing snow, slush, ice, orthe like.

Another prime object of my invention pertains to the arrangements ofparts whereby my apparatus may be utilized with the standard windowconstruction, employing either the windowsill, the tops of bothwindowsashes, or a separate support as a fulcrum means.

A further important object of my invention resides in the versatilecharacteristics of my invention whereby the same may comprise a completeinterconnected utilize a standard rake, hoe, or the like tool inattached association therewith.

Still further objects of my invention relate unit, or may be adaptedtoto the simplicity of'its construction, its adaptability, and itsinexpensive-cost.

Fig. 3 is a cross-sectional view on the line 3 -3 In the drawingswhereinlike flgures represent likefparts, the' numeral'lfl designatesgen- 15 1 struction including a roof I'l gutter l2, window- "frame '|4upper and lower window-sashes l5 "and 5 respectively, windowsill l1,side wall l8,

erally a building having the usual standard conand flooring l9. v

"eferring' specifically to Figs. 1, 2, and 3 which illustrate thei'ireferred-form of my invention, I show my snow removal device ascomprising one complete foldable unit in combination with a separatesupport therefor and present a clear picture of the same in operativeposition.

In this particular form, I provide a suitable snow-removing element,preferably a rake-like member, as shown, comprising a shaft portion 20and a rake portion 2|, said shaft portion 20 being appropriately curvedor bent and of sufficient length to be projected above the roof H by anoperator 22 so that the rake portion 2| will properly contact the snowdeposit 23, and be in desired snow-removing position. The bottom of saidshaft 20 is pivotally secured to a socket member 24, into which isthreaded or otherwise attached one end of a lower supporting rod 25, theother end of which rod is formed in the shape of a body brace 26,preferably curved, as shown, to fit conveniently against the thigh ofthe operator 22. Adjustably secured about the shaft 20 above the member24 is a collar 28, the open part of which encloses one end of an upperoperating rod 30 and is pivotally connected therewith by a suitableadjusting pin 29. I

The opposite end of said rod 30 is pivotally fastened to a cross-lever32, said lever, in turn, being formed with hand grips 33 and 34 on eachend thereof, the lower grip 33 being pivotally connected with said rod25, as clearly shown.

If desired, I may rest the lower rod 25 on the inner part of the windowsill l1, using the same as a fulcrum, or I may provide a convenientsupport such as shown in Fig. 2, comprising a unit in proper balanceduring the snow-removing operation, I provide a suitable strap 39 whichis adapted to fit'over the shoulder of the operator 22 and which isattached to the rod 25 adjacent the body brace 26 by any appropriatemeans such as a rivet or pin 40.

When utilizing my novel apparatus to clear a ccumulation of snow 23 fromthe lowerse'ction' of a roof ll adjacent the gutter l2, I-ini'tiallyraise the lower sash l6 and, if desired, .secure the clamp 35 to thesill I1. I then project my unit 'thru the thus open window while yet infolded zassem-lbly with the shaft portion 20, supporting rod 25,operating rod 30, and operating lever-32 insubstantially parallelrelation, positioning the rod 25 between the rollers Gil-38 on thepostSl, or.resting the same on the windowsill l1. Thus.v arranged loperate the -lever-32 into vertical position by means .of the.handles33=and 34, thereby automatically elevating the' shaft. 20 suffi-.ciently-- so that by slight manipulation I; may .ma-neuver the rakeportion 21 into contact with the snow 23, as desired. l

N ow, flitting the strap-#22 over my shoulder and adjusting the brace 26against my thigh, I; am

.prepared to commence thesnow-removal operav.tion. :Ofmcourse, such snowclearance may be effected in; many ways but I find a practical methodisito grasp each grip 33 and 34, and with the lever :32 in verticalposition, holding such grips rigidly while advancing a few steps towardthe open window until the rake portion -2l carries the snow 23, beyondthe roof- II and gutter I 2.

Therake2l is then remaneuvered intosnow-removing location on the roofII, and the process repeated.

It will further be apparent that a person operating my invention needhave no skill to manipulate the same but may easily maneuver the rake,hoe, or similar scraping tool into desired snowremoving position on theroof. In fact, with my device, an operator may whip the rake or hoe withsufiicient force to penetrate crusty snow or ice, which is oftena'mostd'es'irable consideration.

Iclaim:

As a new article of manufacture, snow-removal apparatus of the kinddescribed for use on build- .ingv roofs and operable thru a window fromwithin the building, comprising in foldable association a horizontalwindow-sill contacting member, a roof-engaging snow-removing memberpivoted thereto and extending upwardly therefrom, a

7 Number hand'lever having one end pivoted to the inner end of saidhorizontal member, and a connecting .rodsubstantially parallel to saidhorizontal memberand having oneend pivoted to said ihand leverat a pointspaced from the horizontal member pivot, and the opposite end adjustablyand pivota lly" clamped to said snow-removingo memher, at a point spaced.from its lowermost end, whereby relative rocking movement .of the handlever on its pivot at theinner end of the "horizontal member willactuatethe snow-removingmember. i-
